DONET (Dense Oceanfloor Network System for Earthquakes and Tsunamis) is a unique development program of submarine cabled real-time seafloor observatory network. This program has aimed to establish the technologies of large scale real-time seafloor research and surveillance infrastructure for earthquake, geodetic and tsunami observation and analysis. The first phase of this program has been carried out since 2006 with the purpose to monitor the hypocentral region close to Nankai trough and the installation of observational equipment on 20 stations at Kumanonada has been completed in 2011. The second phase (DONET2) has also started to cover a wider region in 2010. Totally 29 observatories are planned to be installed at offshore Kii peninsula for DONET2 and 2 additionally at Kumanonada for DONET.
